Today Rarlab has just released the latest beta of version 5.3 beta 1 to the public. This time they have finally added and support 7zip extension. (001,002,003,00x and 7zx one)

So I have removed some part of my tweak, not to complicate things.

Here are the full changelog and download

Version 5.30 beta 1
1. Added extraction of multipart ZIP archives created by 7-Zip.
Such archives have .zip.001, .zip.002, ... file extensions.
You need to open .zip.001 file in WinRAR shell to browse
or unpack such archive. All parts must be stored in the same folder
before starting extraction.
2. Added extraction of files split to multiple parts with .001,
.002, ..., extensions. You can open .001 file as a usual archive
and then unpack its contents. WinRAR will combine all parts
and save them to extracted file. All parts must be stored
in the same folder before starting extraction.
"001" item is included to "Associate WinRAR with" list
in "Settings/Integration" dialog.
3. WinRAR file list allows to use mouse Back and Forward buttons
or Alt+Left and Alt+Right keyboard shortcuts to navigate
in recently visited folders.
4. Folder wildcards are allowed in RAR command line in file names to
archive. For example:
rar a backup c:\backup\2015*\*
Recursion is enabled automatically for such folder wildcards
even if -r switch is not specified.
5. "Extract" button in SFX archive is changed to "Pause" when extraction
is started, so it is possible to pause SFX extraction and resume it
later.
6. "Skip encrypted" option in "Find files" dialog to silently skip
encrypted archives while performing search command.
7. Archive test command works for tar.gz, tar.bz2 and tar.xz archives.
Since TAR format does not provide file data checksums, WinRAR checks
only validity of GZIP, BZIP2 or XZ container.
8. Adding a new string to WinRAR diagnostic messages window could be
slow and affect the operation performance in case of thousands
of errors. Now it works fast regardless of errors number.
9. New 'R' object for -sc switch defines encoding of console
RAR messages sent to redirected files and pipes. For example:
rar lb -scur data > list.txt
will produce Unicode list.txt with archived file names.
10. Sleep time parameter in -ri<priority>[:<sleep_time>] switch is
adjusted to lower its impact to RAR performance and especially
to recovery record related operations. Higher sleep time values
are needed to reduce the system load to same level as
in previous versions.
11. Console RAR "l" and "v" commands display file time in YYYY-MM-DD
format.
12. When extracting RAR and ZIP archives created in Unix, WinRAR maps
decomposed Unicode characters to precomposed. Such conversion
is required for some Unix and OS X archives to correctly unpack
non-English archived names in Windows. It works for Windows versions
starting from Windows Vista.
13. Modification time is set for all folders created when unpacking
.7z archives. Previous versions set it only for non-empty folders.
14. WinRAR prevents a computer to go to sleep by inactivity timeout
until current operation, such as archiving, extraction or another
archive processing, is done.
15. Total progress bar is displayed when extracting .arj, .lzh and .cab
archives (except multivolume archives).
16. Progress bar is displayed when deleting files after archiving
and when clearing "Archive" attribute of archived files.
17. "Test" command also verifies contents of NTFS alternate data streams
in RAR 3.x - 5.x archives. Previously their contents was checked
only during extraction command.
18. Bugs fixed:
a) console RAR crashed instead of displaying an overwrite prompt
when attempting to add files to already existing volumes;
b) console RAR "lt" command did not display seconds in file timestamp;
c) WinRAR failed to decompress .xxe files if they did not include
"section N of xxencode" string in the body;
d) RAR could not restore contents of NTFS alternate data stream
saved with -os switch if it was split between different volumes.

WinRAR - What's new in the latest version
Version 5.21
1. "Drag and drop context menu" options in "Settings/Integration/
Context menu items" dialog allow to disable WinRAR archiving
and extraction commands in context menu displayed after dragging
and dropping files with right mouse button.
2. If winrar.ini file is present in the same folder as WinRAR installer,
winrar.ini will be copied to WinRAR program folder after completing
installation.
3. While previous versions could produce RAR5 volumes of slightly
smaller than requested size sometimes, such situation is less
likely now. In most cases volume size equals to specified by user.
4. Now by default WinRAR skips symbolic links with absolute paths
in link target when extracting. You can enable creating such links
with "Allow absolute paths in symbolic links" option on "Advanced"
page of extraction dialog or with -ola command line switch.
Such links pointing to folders outside of extraction destination
folder can present a security risk. Enable their extraction only
if you are sure that archive contents is safe, such as your own backup.
5. Bugs fixed:
a) WinRAR 5.20 issued unnecessary user account control (UAC) prompt,
when running an executable from archive stored in UAC protected
folder. Since nothing is extracted to folder containing an archive
in such case, UAC prompt is not needed;
b) WinRAR could overwrite files with read-only attribute only
when unpacking RAR and ZIP archive formats. Now it is also
implemented for other archive formats supported by WinRAR;
c) "Elapsed time" and "Time left" were displayed incorrectly
when applying "Convert" command to multiple archives
and enabling "Add recovery record" option.

I just upgraded my Windows 8.1 on Alienware 14 to Windows 10 Preview today. What I found is that there are many changes in OS upgrade process, where there is no compatibility issue I used to face back in the old days. Microsoft has really really improved theirs tech on this and I am very impress. The OS is fluid, every single functions work perfectly just like they should be. I also can’t deny that I’m feeling some influences of the flow and UI from the OSX. However, Windows 10 is completely overthrown the OSX premiumness at this point.

I have complete no doubt that this will be the next big thing for 2015, and it will completely changes the face of the current Windows platform forever.

Such links pointing to folders outside of extraction destination
folder can present a security risk. Enable their extraction only
if you are sure that archive contents is safe, such as your own backup.
2. Bugs fixed:
a) if several files from different folders were selected
and extracted using "Flat folders view" file list mode
and "Extract relative paths" extraction option, WinRAR could
truncate paths of some of these files. It did not happen
if entire file list contents or a single file was selected.
Version 5.21 beta 1
1. "Drag and drop context menu" options in "Settings/Integration/
Context menu items" dialog allow to disable WinRAR archiving
and extraction commands in context menu displayed after dragging
and dropping files with right mouse button.
2. If winrar.ini file is present in the same folder as WinRAR installer,

We are approaching the end of year 2014, again just another year is passing by. This year has been an exciting year for us since next year the new chapter of Windows OS will once emerge again. I hope you all have purchased your own license and get ready for the update.

I would like to wish you and your family a wonderful Holiday and a Happy New Year! See you again in 2015!

I’m proud to announce the latest release of WinRAR 5.10 Final corporate version to you all.

Please see the changelog below:

WinRAR - What's new in the latest version
Version 5.10
1. Added extraction support for ZIP and ZIPX archives using
BZIP2, LZMA and PPMd compression.
2. Added extraction support for 7z split archives
(.7z.001, .7z.002, ...).
3. Added support for AES-NI CPU instructions allowing to improve
RAR encryption and decryption performance.
4. Default theme images are scaled up with better quality
in high DPI display mode.
5. Environment variables, such as %temp%, can be used
in "Files to add" field of archiving dialog.
6. Switch -ai can be used when creating RAR archive,
so predefined values, typical for file and folder,
are stored instead of actual attributes.
Previously this switch could be used only when extracting.
